Synchronizing Audio with Screen Entry
Redesigned the playback pipeline so that audio initialization and screen transitions are consistently aligned from app launch through video playback.
During the flow from splash and onboarding through to content screens, a timing mismatch existed between screen transitions and audio readiness. In some cases, track loading lagged behind video playback; in others, audio was prepared before the corresponding screen had fully rendered.
To address this, screen layout work and playback pipeline redesign were treated as a single scope of change. In segments with continuous short-form video, audio session initialization and track loading were aligned to the same point in time. Mount state and Now Playing metadata were consolidated to reference a single source of truth. The spatial and reverb effect chain was also integrated directly into this playback pipeline so that audio enters at the same moment as the screen transition.
This class of mismatch operates at the sub-frame level and does not surface in feature specifications, but it directly degrades the consistency of the playback experience. When video and audio arrive at the same moment on screen entry, the app's responsiveness and reliability improve measurably. The objective of this work was to guarantee that consistency.
